Abstract: The purpose of this paper is to present an integrated joint application of Life Cycle Analysis (LCA) and Data Envelopment Analysis (DEA) in order to evaluate the efficiency of different end-of-life treatment options for wind turbine decommissioning, considering, technological, economic, and environmental aspects in a circular economy context. Eleven scenarios have been configurated concerning the material waste management of a representative type of wind turbine operating in Greece. Mechanical recycling, landfill disposal and advanced thermal recycling technologies, such as conventional or microwave pyrolysis are addressed. The proposed approach does not only evaluate the efficiency of each one of the different end-of-life treatment processes relative to one another, but it also suggests circular economy-driven policy-making scenarios towards more sustainable waste management in the country. Real-world data calculations indicate that improving the performance of the energy-intensive thermal recycling process could maximize the environmental benefits. Α circular zero-waste approach based on remanufacturing, repurposing or waste prevention through design-for-recycling of wind turbine blades, could also favor long-term sustainability.
